Engineering:Advent Video Beam Television

From HandWiki

The Advent VideoBeam is a big-screen television that was invented in the 1970s by Advent Corporation, founded by Henry Kloss. Both picture and sound are projected from the television's projector base towards a curved screen, where they are reflected back towards the viewer. It is a plug-and-play system, which means it has few adjustments, to make it easier to install.[1] In 1978, its advertised sale price was $3,000.[2]
